Question

Two litres of water are poured into an empty rectangular tank of length 25cm and width 20cm.

The water completely fills the tank, without it overflowing.
calculate the depth of the tank

Answer 1

1 litre = 1000 cm³

thus, 2 litre = 2000cm³

volume = lbh

2000cm³ = 25 x 20 x h

2000cm³ = 500 x h

Thus, h = 4 cm.

Thus, the depth of tank is 4 cm

Answer 2

1000 cubic cm = 1 liter

V=WHL
2000 cubic cm=W(20)(25)
2000 cubic cm=W(500)
2000/500 = 4

depth = 4cm
